Keynote Text Gradient Fill Not Showing

I am trying to change the gradient text color in Keynote. I have seen videos online of people changing gradients and whatnot, but that option is not available. I can edit the color of the text plainly by clicking the color wheel, but I cannot change it to anything more complex. I see how to do it in pages. Is this no longer a function in keynote? Here is a picture of the screen. The online tutorial said it is a thing I can click under the font menu.
